Let's start by talking about those we have lost.

Bo Schultz

Originally an Oakland pick, Schultz was an independent ball pickup for the Diamondbacks in time for the 2012 season, and spent most of the year in Reno, putting up a 6.18 ERA there in 135.1 innings (23 starts, five relief appearances). However, he was part of the roster for the Australia trip, and made his major-league debut in the second game down under, working a scoreless inning. He was also called up for a spell at the end of July, but that didn't go as well. Over three appearances and seven innings, he allowed seven earned runs on 12 hits and a walk, with five strikeouts. His Diamondbacks ERA ends at 7.88.

Roger Kieschnick

Kieschnick was a waiver-wire pickup from the Giants on April 4, having appeared in 38 games for San Francisco last year, with a .521 OPS. But he was more a poster child for the illusion which are Reno stats. For the Aces, Roger looked decent,  with a line of .260/.317/.461 and 15 homers in 95 games. But over three spells with the D-backs, in April, June/July and August, Kieschnick hit below the Uecker Line, batting .195 (8-for-41), with no walks, 16 strikeouts, and an OPS of .488. In his defense, more than two-thirds of his 25 appearances were in the notoriously difficult role of a pinch-hitter, but he didn't produce enough to deserve any more playing time.

Alfredo Marte

Marte saw some playing time last year, but didn't do too much, hitting .186 over 48 plate-appearances. He saw more in 2014, particualrly in August when he started 16 times, but the results were no better, Alfredo hitting .170/.221/.292 for a .514 OPS. At age 25, he's still fairly young, but the rise of David Peralta basically made Marte surplus to requirements, since he's no higher than sixth on our depth-chart, behind Ender Inciarte, Peralta, A.J. Pollock, Cody Ross and Mark Trumbo. Marte's .174 batting average for Arizona is the lowest, by 20 points, of any D-back with at least 150 plate-appearances.

Schultz is the only one I feel a vague tinge of regret at losing, simply because starting pitching is a commodity of which you can never have too much. Meanwhile, the Pacific Coast League transactions page shows three other Diamondbacks went unclaimed, and have been outrighted to Reno: outfielder Brett Jackson, catcher Bobby Wilson and left-handed relief pitcher Joe Paterson. All three saw a very light sprinkling of action: Jackson got five PAs, Wilson four, and Paterson threw 1.1 innings, allowing five earned runs for a 33.75 ERA. If we see any of them in 2015, it probably means something has gone awry, higher up the chain.
